Turf shoulders are provided along both sides of a greenway trail to provide a safe run-off area for pedestrians and cyclists.
The image to the right shows this typical condition. Standard turf shoulders extend a minimum of 3’-0” from the edge of the trail. However, based on feedback from the maintenance partner involved, the shoulder can be widened for specific maintenance requirements. If conditions do not allow for proper shoulder width, the shoulder or the trail itself should be narrowed based on safety considerations.
- These areas are graded at a maximum of 12:1.
- Seed is generally preferred. Hydroseeding with tackifiers is preferred. For standard seeding, straw mats or other measures should be utilized to prevent seed migration.
- Sod should be used where conditions require more immediate turf establishment. Finished grade (top of sodded or seeded soil) should be 1/4” to 1/2” below trail edge to provide for adequate drainage.
- Ensure that soils meet specified condition.
- Grading to be reviewed by design team prior to placement of seed or sod.
PREFERRED SPECIES: Turf-type tall fescue (Improved cultivars)
Other turf-grass species may be considered where conditions require it. Buffalo grass sod could provide a lower maintenance alternative to traditional turf grass, where appropriate.
